CUTTING-INSTRUMENT.

ESPEOIFICATION forming part of Letters Patent No. 342,258, dated May 18, 1886.

Application filed August 23, 1885.

To aZZ whom 21? may concern.-

Be it known that I, C. RAYMOND HEIZMANN, of the city of Reading, State ofPennsylvania, have invented certain Improvements in Out 5 ting-Instruments, of which the following is a specification.

My invention has reference to cutting-instruments especially adapted for the use of tobacconists, druggists, and others; and it conl sists in certain improvements, all of which is fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof. In most cutters of this class, commonly known as. tobacco-cut 1 ters, the sash which carries the knife is forced down, directly or indirectly, by a cainlever, and is raised by means of springs; or the sash is connected to the lever by links or other complicated parts liable to derangement or wear,

and which are expensive in their construction.

My object is to simplify the construction of machines of this nature and make them more durable.

In carrying out my invention I provide the bearing and a rack-bar, and make the lever for moving said cutter with a cam and a pin ion-segment to work in conjunction with the cam-bearing and a rack on the cutter, the parts 0 being so shaped or formed that the cam alone depresses the cutter While the pinion alone raises it. When the cam is operating, the pinion is out of contact with the rack, and when the pinion is in action the cam is out of contact 5 with the bearing on the' cutter-blade. By this means an absolutely positive and smooth reciprocation is given to the cutter-blade. The

cam operates where the greatest power is required, while the rack and pinion have the In the drawings, Figure 1 is a side elevation with part of the framing broken away, of a cutting-instrument embodying my invention; and Fig. 2 is a plan view of the same.

4 5 A is the base-plate, and B is the hollow archframe, secured thereto bybolts D. Said frame B consists of two sides plates, 12, secured together by rivets O, and having the guidefaces E for vertically guiding the cutter- 0 blade.

tween the guides E and carries the cutterblade G, the latter being secured to it by screws I-I, passing through slots g, whereby it may be vertically adjusted and secured in position.

Adjusting-screws I pass through the upper part of the sash F and press against the cutter-blade, so as to adjust and hold it vertically to insure a clean and even cut. The upper part of the sash is provided wit-h the cambearing face It and the rack-bar J.

L is a handlever for operating the cutter, and is pivoted between the said plates of the frame B at M, and is furnished with a cam, K, adapted to work in contact with the bearing it, and is further provided with a pinionsegment, N, adapted to mesh with the rack J. Normally working, the cam K works against the face k of the sash, and positively forces the blade down through the material to be cut; but in raising the sash the cam plays no part, but is free and clear of the face it, and the pinion N, meshing with the rack J, positively raises the sash and its blade. IVhen cutting, the pinion does not touch the teeth of the rack; but when raising the sash the upper face, a, of the pinion-teeth works against the under face, j, of the rack-teeth. From this it is seen that when the cam is actuating the upper sash the pinion plays no part, and when the pinion is actuating the sash the cam plays no part.

I do not limit myself to the particular shape or configuration or details of construction given to the various parts, as they may be modified in various ways without departing from my invention.

Having now described my invention, what- I claim as new, and desire to secure by Letters Patent, is-- 1. In a cutting-instrumenha cutter-blade adapted to vertical reciprocation and provided with a cam-bearing face and a rack, in combination with a lever having a cam and a pinion to respectively work in contact with said face and rack, the connection between the parts being very loose, whereby when the cam is working the pinion does not touch the rack, and when the pinion is working in contact with its rack the cam does not touch the camface, substantially as and for the purpose Ioo specified.

In a cut-tinginstrument, a cutter-blade adapted to vertical reciprocation, in combinaand a lever to simultaneously move both the 20 tion with a cam to depress it and a pinion and cam and pinion, substantially as and for the rack to raise it, and a lever common to both purpose specified. the cam and pinion, substantially as and for 5.
